The laryngopharyngeal area is usually dealt in the otolaryngology and can be easily ignored by endoscopists because it is hard to observe due to laryngeal refluxes. Moreover, beginner endoscopists may have damage to the laryngopharyngeal area due to unfamiliar structure and untrained technique. However, a closer observation has to be made, especially when the patient has hoarseness, mogiphonia, bulbar symptom, dysphagia, odynophagia, and dyspnea at inspiration. Laryngopharyngeal lesions that can be observed with the endoscopy include reflux laryngopharyngitis; corrosive lesion; benign laryngopharyngeal tumor such as papilloma, lipoma, cyst, and vocal cord nodule; malignant laryngopharyngeal tumor; and laryngeal cancer.
